Just wanted to clarify some things regarding when modifications of stats occur:
Modifiers like Trick Room, Tailwind, Swift Swim/Chlorophll/Sand Rush, and by extension Thunder Wave, all take effect the turn after they happen, but Quash/After You do not?
I also have some confusion regarding Reflect and Light Screen, but I do not know how to ask them without being really confusing, so here are some probably just as confusing scenarios to try and illustrate what I am trying to say.
Scenario 1, you have a Ferrothorn and the opponent has a Cresselia. This is a new turn. The Cresselia moves first and uses Reflect. The Ferrothorn moves second and uses Power Whip. Question 1: Is this Power Whip at full power or is Reflect factored in the calculation?
In scenario 2, say at the beginning of a turn, you have a Hariyama and a Metagross, and the opponent has a Cresselia, and Reflect is active. The Hariyama is fastest because hypothetical and uses Brick Break, destroying the Refect. Question 2: is this Brick Break at full power, or is Reflect factored in? Next, the Metagross, being the second fastest, goes next and uses Meteor Mash on the Cresselia. Question 3: does the Reflect still linger and thus count in damage calculation, like a speed modifier does when deciding turn order (in my understanding), or will the Meteor Mash be at full power?
Sorry for the basic questions, I just want to make sure my understanding of these concepts is accurate.
